Why the study?
Do cerebral microemboli in patients with mechanical prosthetic heart valves alter cognitive abilities compared to patients with biological prostheses or healthy subjects?
Do cerebral microemboli in patients with mechanical prosthetic heart valves alter cognitive abilities compared to patients with biological prostheses or healthy subjects?
Cerebral microemboli in patients with mechanical heart valves are associated with a deterioration in working memory, whereas episodic memory alterations may be related to the long-term effects of the surgical procedure itself.
No takes yet. Share an insight, caveat, or question.
Microemboli in mechanical valve patients were associated with working memory decline; leaves open causality and need for prospective studies.
Deklunder et al. (1998) studied this question.
